Overview

A packet transmission system, a packet transmission method, a packet update method, a host apparatus, and a computer program product thereof for the packet transmission system are provided. The packet transmission method comprises the following steps: transmitting a first positioning packet that has a first message serial number; receiving the first positioning packet; generating a temporary packet that has a second message serial number; determining that the first message serial number is smaller than the second message serial number; transmitting the temporary packet; receiving the temporary packet and updating the first message serial as the second message serial number; and transmitting a second positioning packet that has the second message serial number. Thereby, the system not only prevents repeat transmission, but also enhances positioning reliability by using two-way transmission.
